You say you have a borg warner rear axel. Does your car have rear disc brakes? It does sound like you have the G92 option, in which case you have a 215 hp 305.

Car: 1987 Z28 Convertible
Engine: 305 TPI
Transmission: 5-speed
We're all leading down the wrong path here. I need to clarify a couple of issues to set things straight.
Firstly, I need to ask a basic question. The car in question is a 1987 Z28, we know this. But does it come equipped with the IROC-Z suspension/graphics option (RPO B4Z)? The availablility of G92 (performance axle ratio) was limited to Z28's WITH the IROC-Z option. Also, the 1987 5-speed IROC-Z's with G92 got the 9-bolt Borg Warner rear axle assembly. All others have the 10-bolt. Here's a breakdown for 1987 Z28's:
Z28
305 TPI Automatic:
2.77 ratio (standard) - 10-bolt
No optional ratio available.
Z28
305 TPI 5-speed:
3.08 ratio (standard) - 10-bolt
No optional ratio available.
Z28
350 TPI Automatic:
Not produced.
Z28 w/IROC-Z
305 TPI Automatic:
2.77 ratio (standard) - 10-bolt
3.23 ratio (G92) - 10-bolt
Z28 w/IROC-Z
305 TPI 5-speed:
3.08 ratio (standard) - 10-bolt
3.45 ratio (G92) - 9-bolt
Z28 w/IROC-Z:
350 TPI Automatic:
3.27 ratio (standard) - 9-bolt
No optional ratio available.
Furthermore, G92 was only available with RPO G80 (limited-slip differential) and J65 (four wheel disc brakes). Also, G80 was a mandatory option with all 305 and 350 TPI engines.
So if the car is a 1987 Z28 without the IROC-Z option, it originally came with a 10-bolt (not a Borg Warner) and G92 was not an option. The 5-speed Z28's received 3.08's with G80 (limited-slip).
No I dont have rear disc brakes... but the previous owner said it was a borg warner rear axel... posi traction..does that mean that both rear wheels spinns at the same time?
Count the number of bolts holding the cover in place. If you do not have rear discs and is the original rear axle, it must be a 10-bolt with limited-slip and 3.08 gears (assuming it is not an IROC-Z).

U are saying u have the BW rear and no Disc Brakes and its NOT an IROC-Z?? That doesn't make sense. I figured it was an IROC when I saw u had the BW rear. If so, the previous post is correct. G92 was only available on IROC-Z's. The owner probably just told u that. U must have the 3.08's and it can't be G92 without Disc Brakes, so I'd say u have an 87 Z28 LB9 5-Speed with the 10 Bolt and not the BW, unless some1 changed the axle.

I thought that the Borg & warner axel came with disk brakes, no other way, drum brakes were not available on the B&W.
I don't know, I am just assuming, but from everything that I have read it seems to be indicating that.

Swede,
You normally don't have to check the RPO codes to see whether your car is an IROC-Z. Here is a short list of items found only on an IROC-Z:
IROC-Z door decals,
16-inch wheels (Z28 wheels are 15-inch),
body-color rockers, otherwise known as ground effects, (Z28 rockers are silver, gold or charcoal),
two-color striping (Z28 striping for 1987 includes three shades of a specific color and black), and
a "Z28/IROC-Z dash emblem (Z28 displays either "Z28" with the carbed engine or "Z28/TUNED PORT INJECTION" for the TPI.
Of course, this all assumes the car is original and not modified but I hope it helps.

IROC rims, Z28/IROC-Z on the dash, Wonderbar, and grill insert with driving lights.

The grill is the same color. Z28's got a different grill with slots while the IROC-Z's were cutout and driving lights were put there. There is also a place for the liscense plate that says CAMARO, the Z28 had to have a separate liscense plate braket put on and had no "place" already made for it.

ACTUALLY, u COULD have that grill insert and driving lights on a Z28, but they had to be specifically ordered on them or u got the regular standard Z28 1. Yup, RPO T96. I just thought about that. This was standard on IROC-Z's and pretty rare on Z28's. This is probably what u have. Still look at your RPO's though.

Well I´m 100 % sure that the emblem on the dash only says Z28... And u are sure that my grill didnt come on the Z28 modells?
Please double check this as it's probably not the "Z28" one, according to what's been said already. If it's a Z28 with TPI, it should read "Z28" with "TUNED PORT INJECTION" in smaller letters under the Z28. If it's an IROC-Z, it will read "Z28" with a smaller "IROC-Z" under it. I can send you pics of all three if you prefer.
I can clarify the issue about the fog lamps and grill with the "CAMARO" lettering. This setup was standard on all IROC-Z's. It was a stand alone option on the 1986 Z28; $60 was the original price. In 1987, fog lamps on a "plain" Z28 were included in option package RPO 1SC (it was not available separately as in 1986). I have this option on my 1987 Z28 ragtop. Regardless of all this, the grill was always gloss black and the "CAMARO" lettering was either silver or gold, depending on accent color of the car.

Car: 1987 Z28 Convertible
Engine: 305 TPI
Transmission: 5-speed
I´m getting real confused now 
Should I be enable to tell by the vin if it is an IROC?
Ordinarily, no. The only way the VIN will be conclusive is through the eighth digit (engine code) ONLY if the engine is exclusive to the IROC-Z. In 1987, the only engine would be the 350 (engine code "8"). But for 305's, the VIN tells nothing.
Because the car has been repainted, all exterior differences between a Z28 and IROC-Z are wiped clean. So here's a review to (hopefully) clarify the difference between a Z28 with and without the IROC-Z option for this car:
Wheels:
Confirm original tire size by examining the tire sticker on the driver's door jam. It lists the original tire size. 15 or 16-inch? 15" = Z28. 16" = IROC-Z. As long as the VIN on this decal matches the car, this is conclusive.
RPO Code:
Found in the center console glove compartment. B4Z = IROC-Z. This is conclusive.
Rear Axle Assembly:
Count the number of cover plate bolts. Assuming it's the original piece, then nine bolts makes this car an IROC-Z with limited-slip (posi, if you will), rear disc brakes and 3.45 gears. If it's true that this car does not have rear discs (again assuming an original rear axle assembly), it must be a 10-bolt. If it is a 10-bolt, this does not mean it is not an IROC-Z, only one without RPO G92 (high performance rear axle ratio).
Dash Emblem:
Z28 will have either a "Z28" or "Z28/Tuned Port Injection" emblem. The IROC-Z will have a "Z28/IROC-Z" emblem.
Wonderbar:
This is a 1/2" diameter frame stiffening bar that's bolted with the same bolts as the front sway bar. Look at your front sway bar (32mm in diameter). The Wonderbar will be just in front and parallel to it between the two mounting bushings.
Fog Lamps:
Inconclusive as it was offered on both.

"I have this option on my 1987 Z28 ragtop."
Willie, could u post a picture of that?? RPO T96 right, u just had it with the 1SC option correct??
Correct. I have RPO 1SC and it includes the fog lamps.
Would you like a pic of the car (side or front) or my original window sticker?

Car: 1987 Z28 Convertible
Engine: 305 TPI
Transmission: 5-speed
finaly I have my rpo codes!
Congratulations!! You are the owner of a 1987 Z28 with a 305 TPI, 5-speed, and a 3.08 ratio 10-bolt rear. (My convertible is equipped the same way.) It is not an IROC-Z as RPO B4Z is not listed. Also RPO F41 is, which is the suspension listing for a 1987 Z28. Also, the tire size is the 15-inch variety (Z28). You also have RPO 1SC, Option Package #3 which includes all power options AND fog lamps (same as me)!!
So to answer your original question whether it is rare; well, it's not rare but it's not common. Most 1987 Z28's had the IROC-Z option which in itself makes the true Z28 uncommon. Then fit it with a 305 TPI and 5-speed makes it rarer.
Unable to locate code 1AZ in our database!
RPO 1AZ indicates the car was originally specially ordered from GM through a Chevrolet dealership, i.e. it was never part of dealership stock. It was delivered to the owner as soon as the vehicle arrived at the dealership and prepped. RPO 1AY will be seen on cars that were for dealership stock.
And once again... thank u very much for all the help
Glad we could help.

p.s. Pics of my ride will be posted shortly.

Sorry for the delay posting my pics. Apparently, webshots where my pics reside, changed the address on all hosted pics. That's why I couldn't get my pics loaded here. I believe I have the problem resolved so here goes:

IROCTWENTYGR8,
Better late than never. It's been on my mind for a while, so I finally did something about it.
I was going to send you an e-mail, but you don't have a link to it. In any case, I'm glad you finally got to see a Z28 (non-IROC-Z) with stock fog lamps. BTW, my polished IROC-Z wheels are not original (but we all know that!!). I just like them better than the stock 15-inchers I have in my storage room.

This is like the 2nd Z28 I've seen with the driving lights. Your IROC rims look gr8. Did you just polish just the outside or polish the ouside and paint the stripes and insides of the rim??

I had only the "outer" surfaces polished. The relief areas are all painted gloss black. You can't see it in these pics, but I did not want any reference to an IROC-Z anywhere on my car, so I took the IROC-Z centercap backing and inserted Z28 caps into them. The Z28 caps are slightly smaller but still fit nicely.
